[PATCH] D86449: [SelectionDAG] Handle non-power-of-2 bitwidths in expandROT

[Sanjay Patel via Phabricator via llvm-commits]

spatel added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/TargetLowering.cpp:6287
+    HsVal =
+        DAG.getNode(HsOpc, DL, VT, DAG.getNode(HsOpc, DL, VT, Op0, One), HsAmt);
+  }
----------------
This can't be right - both shifts are `HsOpc`. We need another test with a variable shift amount to make sure this is correct?
